采樣頻率轉換器
  • sampling : n. 1. 取樣(品),取標(本)〈指行動或程序〉。2. 樣品,標本。3. 剽竊拼湊歌曲。
  • rate : n 1 比率,率;速度,進度;程度;(鐘的快慢)差率。2 價格;行市,行情;估價,評價;費,費用,運費...
  • converter : n. 1. 使轉變[改變信仰]的人。2. 改裝者,改裝品。3. 【冶金】煉鋼爐,吹風轉爐;【電,無】換流器,變壓器;變頻器;【自動化】變換器;密碼翻譯[編制]機。
  1. A 3rd generation converter samples the signal 44, 100 times per second - with a frequency of 44. 1 khz kilohertz. this time resolution exceedingly determines the sound, which we finally perceive : a low resolution sampling or sample rate results in a more muffled sound because quickly oscillating sound waves i. e. high tone are not acquired correctly

    讀取頻率,也就是聲音的采樣頻率,的高低直接影響到我們最後所聽到的聲音,如果采樣頻率不夠高,聽到的聲音會感覺有點糊糊的暗暗的,因為沒有辦法讀取到某些振蕩頻率較高的聲波,也就是高音的部分。
  2. The main chip of the usb interface circuit is a cypress semiconductor ' s product, cy7c64613, which has intergrated usb sie ( serial interface engine ) and enhanced 8051. the oscilloscope module is realized according to the real time sampling principle. it has two signal chunnels and a dual 8 - bit dual a / d converter whose most sampling rate is 40msps, so two signal acquisition can occurs in the same time

    隨后介紹虛擬儀器測試平臺中各硬體模塊設計實現: usb介面的主晶元是cypress公司的cy7c64613 ,此晶元集成了usbsie和8051核;示波器模塊根據實時取樣原理實現,採用雙8位a / d轉換器,提供兩條信號通道,可以同時採集雙路信號,最高的采樣率為40mhz ;信號源模塊採用直接數字合成( dds )原理實現,它所能產生的信號頻率為10hz 5mhz ,最小頻率解析度為9 . 537hz 。
  3. This paper discusses key technology in the digital intermediate frequency receiver with wide band based on software radio, including down - converter on condition of band - pass - sampling, digital down - converter, multi - rate digital signal processing, band - pass signal decimating, and achieves software system simulation based on under - sampling
